TURB INE-ENGINE Specification of Letters Patent.

:Patented Jan. 2s, 190s.

Application filed June 8,1906. S :rial No. 320.871.

T o all whom it may concern:

.Be it known that I, Louis HACHENBERG, a citizen of the United States, and resident of the borough of Bronx, in the city and State of New York, have invented a new and useful Improvement in Turbine-Engines, of which the following is a specificationv My invention relates to improvements in turbine engines and has for its object to provide certain improvements in the construction, form and arrangement of the several parts of the engine whereby the motive fluid may be `directed therethrough in the most economical manner.

My invention contemplates the use of a piston having a plurality of vanes, one or more nozzles arranged to supply the motive fluid and give it velocity and direction whereby the mot-ive fluid is caused to i-mpinge upon the vanes more than once in one revolution of the iston. A

In t e accompanying drawings, Figure 1 a transverse section through the engine in the plane of the line AdA of Fig. 2, looking in the direction of the arrows, and Fig. 2 is a longitudinal central section through the engine taken in the plane of the line B-B of Fig. 1, looking in the direction of the arrows.

The engine shaft 1 extends through central lugs 2 and 3 of the cylinder heads 4 'and 5. The u per half sectionsof the inner and outer cylin er rings are denoted by 6 and 7 and the lower lf sections aredenoted by 8 and 9. In th )present instance, the lower half sections are shown as formed integral with the base 10. A motive fluid inlet chamber 11 is formed between the upper half sections 6 and 7 of the cylinder rings to which a motive fluid is supplied through a fluid inlet ipe 12 from any suitable source, not shown Herein.` A motive fluid exhaust chamber 13 is formed in the lower half sections of the inner and outer cylinder rings, which exhaust chamber is in o en communication with the lower portion o the rotary piston. The rotary piston is shown herein as com rising two disk sections 14, 15, to equalize t e side thrust, their hub sections 16, 17, fixed to rotate with the shaft 1 and annular series of vanes 18, 19. One or more nozzles, in the present instance two nozzles 20, 21, are arranged to supplymotive fluid from the chamber 11 to the piston vanes at the upper portion of the piston and give the motive fluid velocity and direction. The cylinder heads 4 and' are provided with inwardly projecting central portions 22, 23, which fill the space between the hubs 16, 17, of the pistons and the annular series oll piston vanes. One or more passages, in the present instance two passages 24, 25, extend through cach of the portions 22, 23, from the inner side of the piston vanes at the upper portion of the piston to the inner sides c.P the piston vanes at the lower portion whereby thc motive fluid is caused to impinge upon the piston vanes more than once, in the present instance twice, during one revolution of the iston.

In operation, the motive fluid, as or instance steam, is introduced into the chamber 11-through the pipe 12. The steam is then supplied to a predetermined number of piston vanes through the nozzles 20 and 21 which give the steam velocity and direction. The steam then passes through the passages 24, and 25, andl is again directed against a plurality of the piston varies at the lower portion of the piston. From these vanes the steam escapes to the exhaust chamber 13. It will thus be seen that the steam is used as a driving force for the piston more than once during its revolution.

l/Vhat I claim 1s 1. A turbine engine comprising a rotary piston having an annular series of vanes, a motive fluid sppply chamber having one or more nozzles arranged tosupply the motive fluid from the chamber to the outer sides of the' piston vanes at one portion of the piston, a motive fiuid exhaust chamber in .communication with the outer sides of the chamber having nozzles arranged to supply. the motive fluid from the motive fluid chamber to the outer sides of the vanes at one portion of the piston, a motive fluid exhaust chamber communicating with the outer sides of the vanes at another portion of the piston, stationary sections filling the spaces nclosed by :said annular series of Ivanes and' having passages therethrough `sides of' the piston at that portion adjacent 'to the exhaust chamber, whereby the motive fluid is caused toV im inge upon the vanes twice during one revo ution of the piston.

ln testimony, that Iclaim the foregoing` l0 as my invention, l have signed my nume in presence of two witnesses, this'th day of June, 1906.
